Description

As run into an issue #31745 I come with an idea of adding a new type for arguments called abstract. The idea is to have a better error message when a compilerpass need to replace an argument and it did not happened.

Example

For example the translator.default service:

has a argument which need to be replaced. So service definition would look like the following:

 <service id="translator.default" class="Symfony\Bundle\FrameworkBundle\Translation\Translator"> 
     <argument type="abstract">Should be defined by TranslatorPass</argument>
     <!-- ... -->

So when there exist an abstract argument it should error with e.g. Argument "0" is not replaced for service "translator.default" yet: Should be defined by TranslatorPass.
